Underground inclinometer system

Abstract

The underground inclinometer system includes a probe having a displacement measurement sensor measuring displacement of the ground, a cable controller controlling the length of a cable inserted into the ground to move the probe within an inclinometer pipe, and a ground displacement calculator calculating the displacement of the ground by using displacement measurement information measured by the probe and information on the length of the cable controlled by the cable controller.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This U.S. non-provisional patent application claims priority under 35 U.S.C. § 119 of Korean Patent Application No. 10-2017-0032991, filed on Mar. 16, 2017, the entire contents of which are hereby incorporated by reference.DESCRIPTIONTechnical Field[0002]The present invention disclosed herein relates to an instrument for construction and civil engineering work, and more particularly, to an underground inclinometer inserted into the ground so as to measure displacement of the ground.Background Art[0003]Underground inclinometers are used to determine the safety of ground relaxation areas and temporary structures by measuring the location, direction, size, and speed of each of a horizontal or vertical displacement of soil particles due to other influences such as cavitation at the time of excavation or filling and displacement of an underground water level, comparing the measured location, direction, size, and speed with estimated design dis...

AI Technical Summary

Benefits of technology

The patent text describes a new invention for an underground inclinometer cable that has several technical benefits. The cable is now lighter, cheaper, and more resistant to damage because the internal wirings have been removed from the cable, which allows for easier adjustment of the location of the probe. The cable is also more accurate in measuring displacement of the ground even when it is deformed or replaced. The probe can be easily powered and communicated with, and abnormal data can be prevented by stopping movement of the probe when vibrations occur. Additionally, the changes in the ground caused by vibrations can be measured accurately by identifying the movement of the probe through the inclinometer pipe from a rotational amount of a rotating body.

Problems solved by technology

Such a repeated operation causes the cable 14 to be damaged.

The cost of the cable is expensive, and thus, the replacement cost increases.

Further, the cable cannot be easily replaced once damaged, so that the time or cost significantly increase, and it is difficult to accurately adjust the location of the probe 11 because the position of the probe 11 is adjusted according to the length of the cable.
